Alan Lough, Dunbar, said: “Last season Bayern Munich beat Barca 4-0 and they even had the best player in the world that night.”

Lennon got some advice from another caller.

Thomas Barker, Glasgow, said: “He should sell Fraser Forster and buy a decent midfielder because Celtic would receive a good sum for him.”

Mick McCallie, Dumfries, said: “I agree with a caller the other day who said beating Karagandy was our final this season.

“Take the fees and wages for Teemu Pukki, Dirk Boerrigter and Amido Balde and that could have been Jordan Rhodes.”

Lennon was still getting criticised as Paul McCardle, Gourock, said: “Who plays a weakened side in Europe?”

And J Colven, Arbroath, emailed: “Celtic play in a league without Rangers which means there is virtually no competition. Lennon has to be judged on Europe. You’re only as good as your last performance.”

Kris Commons commented in this newspaper yesterday that when Barcelona “see a dying lion, they take advantage”.

Bryce Wilson emailed: “Commons once again opens his mouth and puts his foot in it.

“Maybe he should take a look in the mirror at his p**s poor performance. Putting a decent shift in might have made a difference.”

James Anderson, Dumbarton, said: “Perhaps he could realise staying on his feet long enough to play football could help his team more effectively.”

Previous caller Tony Kerrigan also came under fire for suggesting Celtic go into administration and come back as ‘The Celtic’.

John Erskine, East Kilbride, said: “Next time you’re getting dressed Tony, look at the badge on your shell-suit, it says: ‘The Celtic Football and Athletic Co’, so no need to change.”

James Hamilton, Glasgow, said: “At least we’re not looking forward to a game with Stenhousemuir this weekend.”

But Rangers fan John Flannigan, County Amargh, said: “They got us off the back pages with their humiliation in Spain, flares, Green Brigade and vandalism.”
